According to sources from CSR Ziyang Locomotive Co., Ltd. CSR Ziyang on October 18, China’s first hybrid AC-driven shunting locomotive, independently developed by the enterprise, has recently passed Sichuan’s technological achievement appraisal. According to the appraisal, the locomotive has filled a gap in the domestic hybrid locomotive field, and is up to advanced international standards among similar products. 
　
Hybrid locomotives are railway locomotives that borrow the concept of hybrid vehicles, and power traction motors through the diesel generator set or the battery pack in a separate or combined manner. Due to low fuel consumption and low emission, hybrid buses are hailed as “green” locomotives. In March 2009, CSR Ziyang, in association with entities including CSR Zhuzhou Institute Co., Ltd. and CSR Chengdu Co., Ltd., launched the R & D of China’s first hybrid locomotive. During R & D, on the basis of fully borrowing the existing hybrid vehicle design concepts and technologies in the world, according to the operation characteristics of China’s shunting locomotives for industrial and mining purposes, the entities massively assimilated the advanced design concept of “Harmony” six-axis large-power electric locomotive, and used CSR’s independent “AC-DC-AC” conversion system and battery management system.

According to sources, as the new locomotive can meet the use requirement of locomotives and bring the power potential of diesel engines into full play, it will be widely used in railway station and yard shunting and the internal railway transport of industrial and mining enterprises including iron & steel, petrochemical and coal enterprises, power plants and ports in the future.
